1. Loose warranty if si number aint the same.. Coz si number is written on hardware ( in xu,... Below the battery)
2. Loose warranty
3 . Root can b unrooted...so unroot it before u get to a service center
4. Unlock bootloader - loose ur warranty for sure
5. Any other process - mods and other software modifications leads to lose of warranty

1. Not true, done many times, even sending to don't itself, Si number is not for warranty
4. Not true, can easily go to locked boot loader, always
You will never lose warranty, you can always go back

Sony's website clearly states in capital that
Unlocking ur botlotloader will void ur warranty
And its not like u do anything u retain the warranty jz by flashing any official rom and relocking bootloader
Si number of the software needs to match wid hardware
And if checked ( hardly takes anything to check) will indicate software tempering and a voided warranty
Sent from my ST25i using Forum Runner
Nope, because you can relock it your warranty won't be voided
Also if you keep it unlocked, you will only lose warranty on software, not on hardware.
I have had 3 Sony phones (2 se 1 Sony) I develop on all of them, returned them for warranty like 15 times and never had any issues.
Si number Is only for updates not for warranty, imei is for warranty.
I know all of this, because of my contact by Sony Holland and Sony united States

I think if they use EMMA I finds that your DRM keys are gone, they might void it.
Drm keys arent that important
They are jz meant for some softwares
Correct me if I m wrong
Sent from my ST25i using Forum Runner
It says unlocking may void warranty.
This is what Sony UK told me:
Hi #####, validating the warranty of a handset once the bootloader has been unlocked is done on a case by case basis which is why we are unable to say for definite whether or not the warranty would be voided by doing this.
However, unlocking the bootloader is usually done to load custom roms and unofficial software which does void the warranty in most cases.

hi,
that is only to scare people, with flashtool you can relock the bootloader and and restore to stock firmware.
Emma doesn't give problems, tested it myself
they also won't check for drm keys.
Would u plz explain what is emma
Jz a bit
Sent from my ST25i using Forum Runner
emma is sony's official flash tool. and a question, when we unlock the bootloader via sony's website, sony getting our phone's some informations and imei, isn't it harder to find warranty? can sony's service say "it looks like your bootloader locked but sony says it unlocked before and she isn't virgin anymore"? (with relocked bootloader)

Hi first of all sorry for my poor english!
i have unlocked my xperia ray bootloader using the tutorial on the official sony ericson website losing my DRM data, and flashed using flash tool the official
ST18_4.0.A.2.368_GENERIC_(1248-9545).ftf file and all worked fine until i done the Firmware upgrade over the air and there my pone stopped working..
i have flashed another firmware but nothing
i cannot go even in the fast boot mode, only flash mode.
can anybody help me? pls
I dont think there is anything you can do. I read somewhere that happens when you unlock bootloader on official website and update it over the air. A hard brick i think its called.
Hope im wrong.

another question is there any way for me to turn back to official updates and using track id?
Did you even take the time to read the disclamer that Sony Ericsson has on their Developer site?
Known issues
It is currently not possible to unlock the boot loader for CDMA phones.
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air upgrades. For additional information, check out the hints and tips from the community on the XDA forum.

That answers the reason you bricked your phone.
And as it has been answered a gazillion times. NO NO NO NO. You CANNOT restore DRM or Track-ID. There are other third party apps that do the same thing.
Please note that you may void the warranty of your phone and/or any warranty from your operator if you unlock the boot loader. Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked. Certain functions in your phone might cease to work, and performance might not be ideal. You might also damage your phone permanently. In the worst case, unlocking the boot loader will cause physical injuries or material damage, for example, due to the phone overheating.

That includes but is not limited to: Official updates(especially ICS), DRM, Track-ID.
I'd recommend you did some research before unlocking your bootloader. It will save you a lot of time and stress.
no i readed all the disclaimer, fully knowing what i was doing. and the reason i have done the fota upgrade was only a stupid mistake i have pressed ok on the notification of update, becouse is similar with the market notification of updates, and i was only wandering if some genius in here was able to make the inverse process of the drm data thanks a lot for evrything.

Hi, I was always wondering then in such case you only shouldn't use OTA updates or does update through PC Companion would brick the phone as well? Do somebody might know the answer?
no the pc companion wont let you update, but if it dose (wich is impossible i think) it wil do same thing.. so update your phone with <flashtool only
Do you try to reflash with the stock rom??

i ve read many threads but still noone has given a direct answer to one question
that how to unroot the neov and still not making warranty void .
and if we can unroot the phone to original stock rom then will the warranty be void and why as we have reverted back to factory rom and we have unrooted the phone again....
can anybody comment.......
If you didn't unlock the bootloader you can simply made a factory reset with SEUS.
Every thing should come back as stock.
I have JJ's doctory hybrid rom (stock kernel and locked bootloader) and SEUS recognize my phone.
But I'm not sure if even after a factory reset with SEUS you will mantain root (superuser will be deleted of course)
-----------------------------------
Rooting will not void your warranty
Unlocking bootloader will void your warranty (if you had to go to warranty center they could reject it)
Flashing stock firmware will not void your warranty, it could if something goes wrong in this passthrough and you need to go to warranty center
If you never lashed .ftf (from different region than your original) with flashtool, meaning, you are still on your stock(original/your region) rom, but root-ed, then you can repair your software with PCC or SEUS, and get clean firmware.
If you flashed .ftf with flashtool (from different region then your original), you can edit your build.prop with CDA customization number for your region and then, restart your phone and repair software with PCC or SEUS.
I highly doubt they(service center) will notice if you have firmware from different region then your original, but still to play on the safe side
Where to find CDA number, check this thread: http://forum.xda-developers.com/showthread.php?t=1604559
Good to hear
So we should write down our CDA customization number before flashing *.ftf (to make root process for example).

It's always a good practice to backup everything you can, even stock original firmware, or in this case CDA number.
I still have my original fw on pc
But as I say, I highly doubt they will notice if you have fw for wrong region.. My gf got totally different fw on her X10 mini pro, when she took it to service center
Yeah, but it's always good to be in the right side.
If I known this before...SOMEONE SHOULD WRITE IT IN THE TOP OF THE ROOT TOPICS. Just say "tap *#*#service#*#* and write down everything you can
EDIT: I found that I took screenshot of software info Now I'm writing it on your discussion.

Really??
So, will rooting, removing stock apps or even installing hybrid ROMs based on stock not officially void warranty? (as long as bootloader is locked)
Lets just put it like this.
Every messing with software CAN be a reason for rejecting warranty claim.
Now you can think whatever you want

That's a nice one.
Now, got Madfish's hint about customization, the question is "in which case you can't restore the phone as your specifically original stock?"
To go to the service center (and be almost sure (99,9%) you'll have not trouble)
-unlocked bootloader? (I read something like you can make it will show it is locked, but you can't relock it completely, I'm right?)
-root permissions? (Is doomlord rooting toolkit something saved in the rom, which can be deleted after flashing new firmware?)
-custom rom on stock kernel? (Install backup of a rom from CWM recovery)
-flashing sony's firmware with flashtool? (like upgrade manually to 4.0.4 from GB)
-files of system partition modified with root explorer? (like camera mods and V6 supercharger)
-CWM recovery installed?

Dear XDA members,
i received a sony xps from my provider (T-mobile Holland) it was branded.
After a while i began to root and ****, but a couple weeks a go i flashed just an offical 0.73 NL with no brand, and via pccompanion i updated to ics.
right now i am not sure if i relocked the bootloader, this is important for me cuz i want to send it to sony becouse off the yellow tint issue.
i made some printscreen about some info of my sony xps.
Question 1 : is my boodloader locked or not if you dont know how can i check it if it realy is locked
Question 2 : Can i get in trouble for my warranty becouse i changed to branded fw to an unbranded fw wich is just official but is unbranded.
guyzzz please let me know
1.Yes your bootloader is unlocked
2. It is stated on the Sony site that unlocking bootloader may void your warranty.
If you are not sure just try to repair it via pcc,if it's successful that's means its locked or flash the ftf file that re-LOCK it.

hmm after i updated 0.73 to ics via pcc i flashed the relock ftf but as you can see my phone says bootloader unlock allowed (yes) how can i lock this bootloader to make use of my warranty .. right now its frustrating im realy sorry for that

He did.
!= mean that something is not equal,like Allowed!=unlocked means that unlocked is not the same as allowed.
Omg. Noobs. This! And then = means NOT EQUAL.
For example Roses!=Violets, because roses are red and violets are blue... LOL. Hope it helps.
Anyway, it's part of programming, we start thinking that people understand those crazy signs.

If you lock it again you will still see that BL unlock allowed =yes
As i say before use the ftf to lock it then use pcc to repair it and send it for fixing.

Sony locked bootloader to not unlocking or hacking the phone (after 11w29 they decided to add a new cheap to prevent unlocking)

Hello everyone..
After using ics in my xperia u, I felt its pretty laggy...
So im thinking of unlocking the bootloader..my only doubt is whether after unlocking the bootloader, I completely lose warranty or not..
Does relocking the bootloader restore the warranty or not?..ive seen that for unlocking bootloader, a code is needed which involves provision of Imei no., so does sony store the details in their servers about which phone's bootloader has been unlocked?
Any help will be greatly appreciated!
Cheers..:good:
If you unlocked your bootloader, your warranty completely gone. If you know how to relock your bootloader back, then your warranty will restore back if the Sony service centre does not know you unlock bootloader.... unlocking boot loader needs your imei number so they can give you the bootloader code... sorry, my explanation very messy!!! Hope you understand it!!!

I guess this is relevant...
I unlocked the bootloader of my Xperia Neo in order to install custom roms / kernels. Later I noticed that my screen had some objects burnt in it (most likely due to excess heat).
I reverted to stock firmware, relocked the bootloader and sent the phone for warranty repair. They replaced the screen and the touch panel, no questions asked.
In my case, there were no problems with the warranty despite the previously unlocked bootloader. Note that the situation might not be the same for you (different problem, repair staff etc).
In other words, there is a chance that unlocking the bootloader voids the warranty of your phone. It is up to you to decide whether it is worth the risk.

Yes there are traces left behind if you unlock and relock your bootloader-its the DRM keys.They are lost forever once you unlock your bootloader and even if you relock your bootloader,they won't get back.
And if a service center checks for DRM keys,then they'll surely know that the bootloader has been unlocked and you cannot invoke your warranty.
Does testpoint method work on 2012 models? Bcoz that method unlocks BL without loss of DRM keys.
Guide says it works on 2011 models, but doesn't look updated. And anyhow phones with fixed battery will not be able to use it anyhow.
